+# MiauInv - Inventory and Project Management System
+
+MiauInv is a secure, light-weight inventory, stock, and project allocation tracking system written in Go. It utilizes HTMX for a dynamic, reactive single-page experience over traditional server-rendered HTML blocks, backed by an encrypted JWT and dual-token refresh architecture alongside an embedded SQLite instance.

+## Technical Specifications
+
+* **Backend Language:** Go (Golang 1.22+)
+* **Frontend Interactivity:** HTMX (v2.0.4) & Vanilla JavaScript (API Client integration)
+* **Database Engine:** SQLite (via standard driver dependencies)

+
+---
+
+## Architecture Overview
+
+MiauInv splits responsibility cleanly across modularized architecture packages:
+
+* **`main.go`**: Entrypoint initializing components and connecting layers.
+* **`server/`**: Configures variables, spins up TLS mechanisms, and exposes route endpoints.
+* **`auth/`**: Custom HTTP Middleware interceptors validating JWT signatures and parsing sub-claims.
+* **`handlers/`**: Core API Controller actions processing CRUD functions on database entities.
+* **`storage/`**: Direct abstraction queries interacting with the underlying SQLite database schema.
+* **`frontend/`**: Serving standard static assets and injecting structural data into components.
+
+---
+
+---
+
+## Detailed Documentation
+
+For deep dives into specific subsystems, database layouts, and security mechanisms, please refer to the dedicated documentation files:
+
+* **[Database Schema & Integrity](docs/DATABASE.md):** Comprehensive breakdown of the SQLite table structures, fields, and foreign key relations.
+* **[Authentication Architecture](docs/AUTHENTICATION.md):** Detailed explanation of the dual-token rotation flow, JWT lifecycle, and frontend loop protection.
+
+## Configuration
+
+The system uses a combination of a structural JSON configuration file and environment variables for system runtime flags.
+
+### Configuration File (`config.yaml`)
+
+The application automatically creates or reads a configuration file named `config.json` in the working directory on startup.
+
+```yaml
+port: "8080"
+database_path: ./appdata/database.db
+certificate_path: ./appdata/cert.pem
+private_key_path: ./appdata/key.pem
+allow_registration: true
+```
+
+### Environment Variables
+
+For cryptographic functions, a mandatory environment variable must be exported before executing the binary:
+
+| Variable | Type | Description | Minimum Requirement |
+| --- | --- | --- | --- |
+| `JWT_SECRET` | String | Symmetric secret signature key used to sign access tokens | Minimum 32 characters |
+
+---
+
+## Route and Endpoint Matrix
+
+All communication with the application happens over defined HTTP transport interfaces. The routes are divided into User-Facing Views (HTML renders) and programmatic Data Hooks (JSON APIs).
+
+### Frontend Web Routes (HTML Views)
+
+| Route Path | HTTP Method | Auth Required | Description |
+| --- | --- | --- | --- |
+| `/` | `GET` | No | Root index landing view. |
+| `/login` | `GET` | No | Renders login page component. |
+| `/register` | `GET` | No | Registration layout or block alert based on authorization properties. |
+| `/dashboard` | `GET` | **Yes** | Aggregated stats layout covering items, projects, and locations. |
+| `/inventory` | `GET` | **Yes** | General overview interface managing stock quantities. |
+| `/items` | `GET` | **Yes** | Standard component interface targeting primary atomic assets. |
+| `/locations` | `GET` | **Yes** | Physical or logical facility structures view. |
+| `/projects` | `GET` | **Yes** | Overview interface listing active construction and logistics operations. |
+| `/profile/` | `GET` | **Yes** | Component context under development. |
+| `/assets/*` | `GET` | No | Serves global minified system design files (`.css`, `.js`). |
+
+### Backend API Endpoints (JSON Serialization)
+
+| Endpoint Path | Method | Auth | Query Parameters | Request/Response Behavior |
+| --- | --- | --- | --- | --- |
+| `/api/register` | `POST` | No | None | Creates a new user record. Requires plain JSON payload containing raw `username` and `password`. Returns status code `201 Created`. |
+| `/api/login` | `POST` | No | None | Performs credential authentication. Sets `access_token` and `refresh_token` as secure, HTTP-Only cookies, and returns user identity metadata. |
+| `/api/refresh` | `POST` | No | None | Accepts JSON containing `refresh_token`. Invalidates previous token structures, rotates identities, and hands over a newly active pair. |
+| `/api/logout` | `POST` | **Yes** | None | Revokes active database-linked refresh session IDs for the user context and drops current browser state tracking. Returns status `204`. |
+| `/api/profile` | `GET` | **Yes** | `id` *(Optional)* | Returns `id`, `username`, and metadata of either the target parameter or active identity mapped from token signatures. |
+| `/api/item` | `GET` | **Yes** | `id` *(Optional)* | Empty parameters fetch all available items with aggregated `allocated` and `available` calculations. Providing `id` isolates a specific item. |
+| `/api/item` | `POST` | **Yes** | None | Inserts a new tracked inventory item schema definition. |
+| `/api/item` | `PUT` | **Yes** | `id` *(Required)* | Modifies values (`name`, `category`, `description`, `total_quantity`) of an active asset by primary key. |
+| `/api/item` | `DELETE` | **Yes** | `id` *(Required)* | Removes an entry. SQLite blocks cascade execution if foreign key assignments still exist in stock or project tracking. |
+| `/api/location` | `GET` | **Yes** | `id`, `content` | Fetching with `id` and `content=true` extracts an array of items grouped at the facility (`item_id`, `name`, `quantity`). Without `content`, returns details or global catalogs. |
+| `/api/location` | `POST` | **Yes** | None | Instantiates a singular distinct location boundary identifier. |
+| `/api/location` | `PUT` | **Yes** | `id` *(Required)* | Renames a location while maintaining foreign keys. |
+| `/api/location` | `DELETE` | **Yes** | `id` *(Required)* | Destroys location configurations if currently cleared of active items. |
+| `/api/project` | `GET` | **Yes** | `id`, `details` | Providing `id` with `details=true` unrolls associated items allocated to that project context. |
+| `/api/project` | `POST` | **Yes** | None | Inserts a tracking context entity for targeted hardware allocation. |
+| `/api/project` | `PUT` | **Yes** | `id` *(Required)* | Updates a project metadata record definition. |
+| `/api/project` | `DELETE` | **Yes** | `id` *(Required)* | Drops an empty project wrapper. |
+| `/api/stock` | `GET` | **Yes** | `id` *(Optional)* | Obtains exact relationship matrices between location nodes and items. |
+| `/api/stock` | `POST` | **Yes** | None | Links allocations across specific site nodes. |
+| `/api/stock` | `PUT` | **Yes** | `id` *(Required)* | Modifies stock metrics directly on specified maps. |
+| `/api/stock` | `DELETE` | **Yes** | `id` *(Required)* | Completely severs relationship entry allocations between nodes. |
+| `/api/association` | `GET` | **Yes** | `id`, `project_id` | Dumps general configuration links, isolated optionally by operational `project_id`. |
+| `/api/association` | `POST` | **Yes** | None | Allocates an inventory batch to a dedicated project infrastructure requirement. |
+| `/api/association` | `PUT` | **Yes** | `id` *(Required)* | Alters active quantity indicators inside a specific deployment matrix. |
+| `/api/association` | `DELETE` | **Yes** | `id` *(Required)* | Frees up allocations, returning tracking variables back to unassigned states. |

+
+## Setup and Deployment Tutorial
+
+### Prerequisites
+
+Before deployment, you must generate SSL/TLS certificates since MiauInv enforces native transport encryption layer communication (or use a bought one).
+
+```bash
+# Create directory for certs
+mkdir -p appdata
+
+# Generate self-signed certificate and private key
+openssl req -x509 -newkey rsa:4096 -keyout appdata/key.pem -out appdata/cert.pem -sha256 -days 365 -nodes
+```
+
+### Option 1: Native Local Deployment
+
+1. Make sure your Go environment path variable properties are populated (Go 1.22+).
+2. Create your environmental token and execute the initialization routine task:
+
+```bash
+export JWT_SECRET="your_minimum_thirty_two_char_secret_key_here"
+go build -o miauinv main.go
+./miauinv
+```
+
+---
+
+### Option 2: Docker Deployment (Recommended)
+
+MiauInv includes container definition orchestrations to package configurations cleanly, binding storage databases outside running containers into persistent volumes.
+
+#### 1. Create the Docker Compose Descriptor
+
+Write the configuration definition mapping layer blocks directly inside a standard file named `docker-compose.yaml`:
+
+```yaml
+services:
+  miauinv:
+    image: git.miaurizius.de/miaurizius/miauinv:latest
+    container_name: MiauInv
+    restart: unless-stopped
+    ports:
+      - "8080:8080"
+    environment:
+      - JWT_SECRET=SECURE_RANDOM_STRING # Must be at least 32 characters long
+    volumes:
+      - ./appdata:/appdata # To edit your configuration files
+```
+
+#### 2. Execution Commands
+
+To bring up your background container image instance pipelines, execute the compose environment controls:
+
+```bash
+# Build and execute the container in background detached mode
+docker-compose up --build -d
+
+# Verify container operation statuses
+docker-compose ps
+
+# Monitor execution system logs
+docker-compose logs -f
+```
+
+Once running successfully via Docker orchestration loops, navigate your web browser context safely to `https://localhost:8080` to interact with your MiauInv control panel workspace.
+
+## Reverse Proxy Integration with Caddy
+
+If you deploy MiauInv behind a global Caddy server, Caddy must act as an HTTPS reverse proxy. Since the MiauInv binary enforces native TLS transport, Caddy needs to be configured to establish a secure backend connection and bypass verification for self-signed backend certificates.
+
+### 1. Docker Compose Network Configuration
+Ensure your MiauInv container shares an external network with your Caddy container (e.g., a network named `proxy`). The container does not need to expose public ports since Caddy communicates with it internally over port `8080`.
+
+```yaml
+services:
+  miauinv:
+    image: git.miaurizius.de/miaurizius/miauinv:latest
+    container_name: MiauInv
+    restart: unless-stopped
+    networks:
+      - proxy
+    environment:
+      - JWT_SECRET=SECURE_RANDOM_STRING
+    volumes:
+      - ./appdata:/appdata
+
+networks:
+  proxy:
+    external: true
+```
+
+### 2. Caddyfile Configuration
+
+Add the following block to your server's `Caddyfile`. The `https://` prefix forces Caddy to use TLS for the backend connection, and `tls_insecure_skip_verify` allows the proxy to accept the internal self-signed certificate generated during the prerequisites step.
+
+```caddy
+inv.yourdomain.com {
+        encode zstd gzip
+
+        reverse_proxy https://miauinv:8080 {
+                transport http {
+                        tls_insecure_skip_verify
+                }
+        }
+
+        header {
+                X-Content-Type-Options nosniff
+                Referrer-Policy strict-origin-when-cross-origin
+                Strict-Transport-Security "max-age=31536000; includeSubDomains"
+        }
+}
+```
+
+### 3. Apply Configuration
+
+Reload your Caddy instance to apply the reverse proxy routing rules:
+
+```bash
+docker compose exec -w /etc/caddy caddy caddy reload
+```

+# Authentication Architecture
+
+MiauInv implements a stateless JSON Web Token (JWT) architecture combined with a persistent database-backed Refresh Token mechanism to provide high security alongside seamless session retention.
+
+## Token Lifetime and Properties
+
+| Token Type | Transport Vector | Storage Location | Lifetime | Purpose |
+| --- | --- | --- | --- | --- |
+| **Access Token** | HTTP-Only Cookie & Auth Header | Memory / Browser Cookies | 15 Minutes | Signed payload validating current session identity for immediate API interaction. |
+| **Refresh Token** | Secure Cookie & JSON Payload | LocalStorage / Secure Cookies | 7 Days | Long-lived high-entropy string used to request a new token pair when the Access Token expires. |
+
+---
+
+## Token Rotation and Flow
+
+The application coordinates token validation through cooperative interactions between Go authentication middlewares and the frontend runtime environment.
+
+### 1. Normal Authenticated Requests
+During standard interaction loops, the Go server intercepts requests via auth middleware. It checks the incoming context for validity in the following order:
+1. `Authorization: Bearer <token>` request header.
+2. `access_token` cookie values.
+
+If a valid, unexpired Access Token is recovered, the middleware parses the claims (ID, username, role) and injects them into the request context before execution routes fire.
+
+### 2. Token Refresh Flow
+When an Access Token expires mid-session, the following workflow occurs automatically:
+1. The backend rejects an API call or routing intent with an HTTP state indicating token expiration.
+2. The frontend execution scope identifies the expiration status and reads the `refresh_token` from storage assets.
+3. The client submits a POST request containing the token payload to `/api/refresh`.
+4. The backend verifies the signature, looks up the hash inside the `refresh_tokens` table, and verifies that `revoked == 0` and `expires_at > now`.
+5. If the validation succeeds, a brand-new Access Token and a rotated Refresh Token pair are generated, saved to secure cookies/storage, and the user session continues without explicit re-authentication.
+
+---
+
+## Security Mitigations
+
+### Loop Protection
+To prevent broken, expired, or malformed credentials from triggering infinite network refresh loops (which degrade browser performance and strain backend lookup performance), the frontend utilizes an explicit safety lock.
+
+
+```
+
+Token Expired -> Check 'is_refreshing' flag -> True -> Clear Auth & Force Login
+-> False -> Set flag 'true' -> Send Request
+
+```
+
+Before issuing an evaluation request to `/api/refresh`, the application checks a temporary session variable (`is_refreshing` within `sessionStorage`). If the flag is already set to `true`, the loop protection triggers a hard clearance routine via `clearAllAuth()`, drops all token storage records, and routes the user back to the primary login view safely.
+
+### Database Revocation
+Refresh sessions can be killed immediately from the server side. When a user requests `/api/logout`, the backend switches the corresponding row state within the `refresh_tokens` database container to `revoked = 1`. Any subsequent rotation requests relying on that token family are automatically dropped, protecting against stolen credential replay attacks.

+# Database Documentation
+
+MiauInv utilizes an embedded SQLite database instance for persistent data storage. Foreign key constraints are strictly enforced at the database level.
+
+## Configuration
+To ensure data integrity, every database connection initialization explicitly executes the following command before handling queries:
+```sql
+PRAGMA foreign_keys = ON;
+```
+
+---
+
+## Schema Architecture
+
+### Entity-Relationship Summary
+
+The database consists of primary entity tables (`users`, `items`, `locations`, `projects`) and relational junction tables (`stock`, `project_items`, `refresh_tokens`) designed to track stock distribution and access sessions.
+
+```
+[users] <--- (1:N) ---> [refresh_tokens]
+[items] <--- (1:N) ---> [stock] <--- (N:1) ---> [locations]
+[items] <--- (1:N) ---> [project_items] <--- (N:1) ---> [projects]
+```
+
+---
+
+## Table Definitions
+
+### 1. users
+
+Stores user credentials and operational roles within the system.
+
+* **id (TEXT, PK):** Unique UUID
+* **username (TEXT, Unique):** Unique account identifier.
+* **password (TEXT):** Hashed user password.
+* **role (TEXT):** Access control flag (e.g., admin, user).
+
+### 2. refresh_tokens
+
+Tracks valid extended sessions linked to specific user accounts.
+
+* **id (TEXT, PK):** Unique identifier.
+* **user_id (TEXT, FK):** References `users(id)`.
+* **token_hash (TEXT):** Cryptographic hash of the active refresh token.
+* **expires_at (INTEGER):** Unix timestamp indicating token expiration.
+* **created_at (INTEGER):** Unix timestamp indicating session creation.
+* **revoked (INTEGER):** Boolean flag (0 or 1) indicating if the session was manually invalidated.
+* **device_info (TEXT, Optional):** Client metadata for auditing.
+
+### 3. items
+
+Represents individual tracked assets.
+
+* **id (INTEGER, PK, Autoincrement):** Primary key.
+* **name (TEXT):** Asset designation.
+* **category (TEXT, Optional):** Grouping classification.
+* **description (TEXT, Optional):** Detailed asset context.
+* **total_quantity (INTEGER):** Absolute global stock baseline counter.
+
+### 4. locations
+
+Defines logical or physical facilities.
+
+* **id (INTEGER, PK, Autoincrement):** Primary key.
+* **name (TEXT, Unique):** Unique facility naming constraint.
+
+### 5. projects
+
+Defines distinct tasks or allocation targets.
+
+* **id (INTEGER, PK, Autoincrement):** Primary key.
+* **name (TEXT, Unique):** Unique operational tracking name.
+* **description (TEXT, Optional):** Scope description.
+
+### 6. stock
+
+Junction table mapping physical asset distributions across facilities.
+
+* **id (INTEGER, PK, Autoincrement):** Primary key.
+* **item_id (INTEGER, FK):** References `items(id)`.
+* **location_id (INTEGER, FK):** References `locations(id)`.
+* **quantity (INTEGER):** Specific quantity present at this location node.
+
+### 7. project_items
+
+Junction table tracking asset assignments dedicated to specific ongoing project environments.
+
+* **id (INTEGER, PK, Autoincrement):** Primary key.
+* **item_id (INTEGER, FK):** References `items(id)`.
+* **project_id (INTEGER, FK):** References `projects(id)`.
+* **quantity (INTEGER):** Quantity allocated to this project context.
+---
+
+## Data Integrity Constraints
+
+* **Foreign Keys:** Because standard `ON DELETE` cascades are not defined explicitly in the schema rules, SQLite blocks parent deletion actions if dependent rows exist in `stock` or `project_items`. You must clear out stock allocations and project associations manually before deleting an item, location, or project.
+* **Uniqueness:** String uniqueness constraints protect against duplicate namespace registration on `users(username)`, `locations(name)`, and `projects(name)`.
